How to tighten up a brushless "bell" motor

|
+0
Once I have seen an article here; its author proposed to overlay output wires of a brushless motor with epoxy resin in order to prevent breaking away and separation of wires in the course of operation...
I do it something differently. As concerns the "bell-type" brushless motors, it is possible to do it much easier and with more elegance.

Here is a little story about how easy it can be to cast parts from an aluminum alloy. Particularly – at home.

Build your first quadcopter

Hello!
I advise you that you let a quadcopter be your first RC hovercraft. Proper setup of its electronic components guarantees its stable work, while proper soldering and correct choice of controllers/motors ensure high integrity. Quadcopters are universally controllable: resembling a helicopter on the one hand (vertical takeoff and landing, thrust braking), a quad’s movement in the air is in a way more similar to an airplane’s. Finally, quads do not require expensive maintenance and are more crash proof. Just a little background with quads enables you to easily switch to any other hovercraft type.

How do I build my first quadcopter without knowing jack about it? Questions you are too shy to ask.

Well, here is my first post about quad- and other types of copters, I hope you won’t be too strict on me. I’ll try to be consecutive and concise about whatever I know about copters. Being a beginner copterologist myself, I’m here to make the whole thing easier for newbies just like me. We are going to discuss:
1. Choosing parts and components
2. Tuning a completed copter
3. Introducing 'aircraft guys’ vocabulary

Replacement of Potentiometers in Turnigy 9X with Hall Effect Sensors

|
+1
Due to age and/or plain poor quality, potentiometers in transmitters tend to gradually fizzle out and potentially cause your most favorite model to crash to death. You can either replace them with new ones or install hall effect sensors instead (named so after a person, not the room type))) and never have to meddle with it again. Here is a list of items we’re going to use:

1. SS495A1 Hall Effect Sensors or similar ones
2. Strong rare earth magnets (10 per package) I used circular magnets, going linear and so all the way down, then shift the magnet’s center a little off from the roll axis. That’s it.
3. A soldering iron (flux and solder alloy)
4. Servo cables (or similar ones)
5. A small cross screwdriver
6. The dexterity of hand)))))

Here is a vid just for a start

"The Hovercraft"

|
+4
Technical title of the project: NaSRu VeSDe (Nanotechnology Supersonic Russian Very Strong Destroyer). Even looking at non-standard vehicle - it is always interesting, but to build with your own hands custom vehicle even more interesting. To this day, I have never designed the hovercrafts, this is the first time. So in this article I will tell everything. Something I managed to do the right way immediately. Something I completely failed. But on some units and mechanisms I had a lot of work. From the theory of hovercrafts I knew only one thing: the hovercraft is lifted by air pressure under the bottom. Therefore, to create maximum pressure, I chose rotor with a lot of blades. Theoretically a rotor with a lot of blades should create a sufficient pressure underneath the hovercraft.

Stand for testing of brushless motors (part 1)

|

I noticed that it is very uncomfortably to use separate devices for testing of brushless motors (servotester, wattmeter - for example). There is a problem: something constantly tries to fall down, wires are got tangled and are trying to make a short circuit. An idea has come to me: combine everything in one device.
I live in Siberia. We have a long winter so in between drinking vodka and walking with a bear... (about vodka and bear it was a joke). One winter evening I had engaged in manufacturing of this device.

Black kites - a beautiful carnivorous Siberian birds. In the summer they always accompany model aircraft in flight. The idea of the film "Black kites in flight" appeared by itself. Black kite is one of the most beautiful birds of Russia.

Hi, everybody! Yesterday I have lifted in the air new Al-609 Dominator model! It flew and flew not too bad. Further it was the period of tests and adjustments before coming to the level of normal pilotage.

I'm in the 10th grade and there are project activities in our school program. I have chosen the topic of physics and wrote about brushless motors. I would like to tell you about my project in this article.
